To all whom it may concern:

Be it known that I, JONATHAN D. MAXWELL, ol' Terrytown, New York, have invented certain l1nprovclments in Universal Joints, of which the following dei gnziting like parts.

This invention relates to universal joints, and is particularly adapted for use in joints for power trainsmittingshalts, although I contemplsty .utilization el my improvements in any field to 'which they ere. adapted by reason of their nature. i'

The object of my invention is' to provide :i joint oi compact form with means v.to enable provision therein be furnished by the forms of Oilers now in use for such joints, my improvements doing sway with the neces` sity for extraneous Oil cups or oil channels which are liable to clog up with dust etc., the oil in my improved joint being contained within the cross ofl the joint ind applied directly to the regions requiringlit, in :mede- My invention includes also means to prevent escape of the oil from the joint and to prevent access of dust to the bearing. Y i

The various features of my invention will be illustmted auddescribed fully in the accompanying druivn the drawings, Figure l is a plain vien( of e universel joint in the construction of which my improvements lieve` been embodied, parts being broken sway to illustrate detsils of construction; and Fig. 2 is a verticel sectional View of the cross of the' joint, seperately, On the line z-x lFig. l.

VIn the embodiment of my invention selected for illustration and description es s convenient form to en-, :ib-le ready and complete und erstzinding of my improve-I" oi a. power transmitting shaft, with the usuel forked firms 2 having threaded sockets 3 in which fairel screwed pins 4 to cooperate With' the cross member. As there lis in the instnce illiistrztted an exactly similar power transmitting member applied to the cross member et ri'ght singles to member l, I have placed thereon, in thev dmwingsthe stime reference numerals to designate `the corresponding parts' which appear in the drawing. l

In eiccordancewith my invention, the cross proper, the `respective i rms ol lWhich are designated in the drawings bythe reference numeral 5, is surrounded bye shell 6 which may be of any convenient form, -but in the instance illustrated is shown us un oblate spheroid in- `virhich are formed relatively large chambers 7, the latter serving esreceptztcles for a large supply of oil and prefemblyrhleingjn communication with each other.

To permit introduction 'of the supply Of oil or other Specieeton of LettersA Patent.

lubricant e.. moutli 8 is provided, with it removable screvr plug 9, e. similar mouth lbeing provided O'n the opposite side of the shell desired, and having n plug ,ll which may be mede removable or not as desired.

To give access of the Oil mintsincd in the chumbers 7 to the bearings l2 inthe cro holes '13 ure drilled or otherwise formed in the nist al ol the cross illustinted et 13, or otherwise :in found suite-ble ind Couven-- ient. `\\"heu constructed es above, the cli-embers 7 hatvinigl been filled with oil, and the shziitcmitaining the joint put in opestionftlie centrifuge-l forcewili cause the larger' portion of the oil to seek the periphery 'of the sphere, but sullicient will lind its Way through the :tperture 13 tO the central splice or feed chamber formed by the intersection oi the continuous cross bearings l2, to supply them amply und lubricante the. members lll ol" the pins 4, this supply being re-ini'orccd by larger quon` tities when the sli-nit is stopped :ind the centrifugal nction cen-ses. l

To prevent es spe Oi the Oil et the heid of the pins, :ind also to exc .ide dust lrom the bearings, l have showjn the bends or' the pins es provided at l5 with n groove containing e, Washer lioi' .felt or other suitable pitching material.

Having thus described my invention, and means by which the seine muy' he carrifdinto effect, l Wish it understood that I do not t myself to :my specific material or shape, in its construction, except setforth in the cleixnsresd in connection With-this specificzttion.

. What I claim and desire to secure by Letters Pnt-ent 1. ln :i cross for universal joints, a member having con- -tinuous cros pivot bearings of uniform diameter throughout aud pio ded with chambers surrounding said bearings to receive lubricant, said bearings forming at their intersection :i feed chunibenthrougli which lubrimint.` is fed from said surrounding supply chambers uniformlyv to the periphores of the pivots. i

. 2. In a device of the class described, u cross hin/ingpivot bearings in its firmsK comprising bores of uniform diameter intersecting' to form :i central feed chamber, :i supply cheminer foi d in the material of said cross surrounding said bearings to receive lnbriczint und having; e. cen 'ally situa-tod feed aperture of relatively smull diamo' i to feedth'e same gradually to said feed chamber and thence uniformly to the peripheries of the pivots lying in snid bearings. substantially as described.

In a'device of the class described, :i cross having benrings in its arms, sind u shell inclusief; sai-d arms and u central feed chamber. with a supply chamber to receive lubrilcunt und feed the stime gradually tol said feed chainber when said device is at rest, and thence to said bearings, substantially :is described.

4. Across for universal joints said. cross consisting ofy un integral member having henri comprising iii-ms will; continuous bearing bores forming ai feed chamber at their intersection, und u cooperating oil supply chamber, substantially as described.

` '5. A device of the class described, comprising anintegrnl structure in the form of nu obiate spheroid, having equatorial cross-bearings', und vchauxbered to receive lubricant, substantially as described. l

'6. A device of the class described comprising a spheroidal structure hving connected equatorial cross-bear irigs, and otherwise hollow to receive lubricant, substantially as described. l

7. vA cross of the class 4described, having pivot bearingswith exterior' piane bearln'g faces adjacent the mouths'of the bearings proper, combined with pivot pins having heads thi-ended to engage and be spported by a yoke /d with bearing faces to coperate with sid cross-bearing faces, -and a packing of felt or the like intermediate said of December, A.
